In Reply to: RE: Would adding an exterenal 47K load through the phono bring it on? posted by 3+4=5 on September 25, 2017 at 22:27:57
I will certainly start with the cleaning and see where that goes.
I would love to send it to arc but there is a big arc dealer here in Montreal with their own techs who work on these old units. I would hope they would use the same transistors from Arc but would have to ask them
If you look at the schematic, the 49.9kohm resistor is *soldered* to the PCB. It is the other values that are connected in via the switch.
It is 99.9% chance that the input JFETs have gone bad. As long as the local dealer can get the correct part from Audio Research, this will be the way to go. I would guess this will cost around $200, as most shops are aroun $100 per hour. Good luck!
Very kind of you. Thank you for your help.
Many audio companies do have other facilities for outside the USA.
Same for Bryston. They have a facility in USA. so not cross border duty confusion.
SO hopefully the dealer in Montreal can work on it if the cleaning does not fix it.
Thanks a lot for your input. Will let you know how it goes.
Hi...i am a new user here. As per my knowledge Switching tubes around changing the sound is just normal tube oddness.The failure is in the switch itself. Most likely some sort of fault to ground at the 47K position.Replace the switch and I bet all will be well.
